Cyanine recording dyes

DVD-R is a "write once" technology that can be used in DVD-RW recorders and  read by nearly any computer DVD drive or DVD player. DVD-R media uses  only cyanine recording dyes which appear violet on the recording side of the disc. 

The laser of your DVD-RW drive heats the dye to a temperature of about 200  C, irreversibly melting a pitted pattern into the recording layer. A  plastic layer alongside the dye expands into the newly available space  creating a pit pattern similar to that of a conventional DVD. Your DVD  player reads this highly reflective pattern for playback. Because the  plastic layer melts into the dye layer to set the pattern, DVD-R discs  cannot be re-recorded. 

Unlike a stamped DVD, DVD-Rs are manufactured with a spiral groove (like a  phono disc) called the pregroove. It provides a precise track for the  writing laser to follow. A DVD player depends on following the recorded  track of pits in order to track the spiral path. 
 
A slight wobble in the pregroove in a pre-established pattern generates a frequency used as a carrier signal; the timing information helps  regulate servo motors, tracking of the laser assembly, and focus of the  beam. Land pre-pits molded into the substrate provide address  information and pre-recorded data, used to initiate write operations.

The larger storage capacity of a DVD-R compared to a CD-R is achieved  through a smaller pit size and smaller track pitch of the groove spiral  which guides the laser beam. Consequently, more pits can be written on  the same physical sized disc. In order to write smaller pits onto the  recording dye layer a red laser beam with a wavelength of 650 nm (for  general use recordable DVD, versus a wavelength of 780 nm for CD-R) is  used in conjunction with a higher numerical aperture lens. Because of  this shorter wavelength DVD-Rs use different dyes from CD-R to properly  absorb this wavelength. 

DVD-R discs are composed of two 0.6 mm polycarbonate discs bonded with an  adhesive to each other. One contains the laser guiding groove and is  coated with the recording dye and a silver alloy or gold reflector. The  other layer is an ungrooved "dummy" disc to assure mechanical stability  of the sandwich structure and compatibility with the compact disc  standard geometry which requires a total disc thickness of about 1.2  mm. 
 

Two methods are typically used to bond the two substrates together:

  • Hot-melt  method: A thin coat of melted adhesive is spread over each substrate and then the two surfaces are bonded by means of a hydraulic ram.
  • UV method: A  thin layer of lacquer is distributed over the disc surface to be bonded, either by rotating the disc or through silk screening. Ultraviolet  light is then applied to harden the lacquer.
The sandwich structure also helps protect the data containing layer from  scratches by the thick "dummy" disk. Compared to a CD's 1.2 mm of  polycarbonate, a DVD's laser beam only has to penetrate 0.6 mm of  plastic in order to reach the dye recording layer, which allows the lens to focus the beam to a smaller spot size to write smaller pits. 

DVD-R recording requires a more complex write strategy to establish the  appropriate lengths for the pits, which are approximately half the size  of those on a CD-R disc. The spacing between the pits and lands within  the spiral data pattern is also significantly less than on a CD-R disc. 
 

T o compensate for the extra precision required during write operations,  the laser pulses are very carefully controlled, both in terms of  intensity and duration. During recording, the laser is rapidly modulated between the power setting required for writing and the setting used for reading to avoid overheating the media surface and to regulate the size of the mark seared in the dye.

A technique known as Optimum Power Calibration (OPC) is used to perform  test write operations to a specified calibration area on the recordable  media surface and then to read back the test and adjust the laser power  settings to match the recorder to the media. Given the extra precision  required for recordable operations using DVD-R, this feature becomes a  highly desirable addition to any recorder and helps ensure the most  consistent results when performing disc recording.
